Charge is uniformly distributed along a thin stick laid on the x-axis. The stick extends from x=0 to x=b, and has charge density o.
(a) Draw the configuration. Show and label all relevant quantities (e.g. distances, angles, field and force vectors etc.) used in the remainder of the problem.
(b) Find the total charge on the stick.
(c) Find the y-component of the field at the point (x, y) = (0, b). Note, the integral is moderately difficult.
